2SC24970R

Single Bipolar Transistors Overview

The Panasonic 2SC2497 is a silicon NPN epitaxial planar transistor designed for low-frequency power amplification. It operates with a collector current of 1.5 A and dissipation of 1.2 W. The device features a TO-126B-A1 package that eliminates the need for an insulation plate during heat sink installation. Electrical characteristics include a collector-base voltage (V_CBO) of 70 V, an emitter-base voltage (V_EBO) of 5 V, and a transition frequency (f_T) of 150 MHz at 200 MHz test conditions.

Single Bipolar Transistors Feature Summary

• Utilizes a TO-126B-A1 package structure that allows direct mounting to heat sinks without requiring separate insulating plates.
• Engineered specifically for low-frequency power amplification applications within standard electronic equipment.
• Complies with the RoHS Directive (EU 2002/95/EC) regarding material restrictions.

Single Bipolar Transistors Applications

• General-purpose low-frequency power amplification circuits
• Office equipment internal signal processing
• Communications equipment power stages
• Household appliance control modules

Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation when ordering, as variants exist with different voltage ratings. Confirm the component lifecycle status on the manufacturer's official semiconductor website prior to procurement, as this product may be subject to planned maintenance or discontinuation schedules. Ensure all design parameters remain within the absolute maximum ratings provided in the technical documentation.

Single Bipolar Transistors Selection Notes

Select the 2SC2497A variant if the application requires a higher collector-emitter voltage rating of 60 V compared to the standard 50 V rating. Consider the thermal management requirements carefully, as the device supports up to 1.2 W of power dissipation only when paired with appropriate heat sinking. Verify that the required forward current transfer ratio falls within the specified Q or R rank classifications.

Single Bipolar Transistors Part Context

This component belongs to the family of silicon NPN epitaxial planar transistors manufactured by Panasonic Electronic Components. It serves as a complementary device to the 2SA1096 and 2SC1096A PNP counterparts. The technology focuses on providing reliable performance for general-purpose power amplification tasks in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Consult the manufacturer's official replacement list for confirmed substitute part numbers. Do not assume functional equivalence with other generic NPN transistors without verifying pinout compatibility and electrical parameter alignment against the original datasheet specifications.

Single Bipolar Transistors FAQ

What is the difference between the 2SC2497 and 2SC2497A models?

The primary distinction lies in the collector-emitter voltage rating. The 2SC2497 has a V_CEO of 50 V, while the 2SC2497A offers an increased rating of 60 V under identical test conditions.

Does the TO-126B-A1 package require an insulator for heat sink mounting?

No, the TO-126B-A1 package is designed to allow direct installation to a heat sink without the necessity of an additional insulation plate.

What are the recommended operating temperature limits?

The junction temperature (T_j) must not exceed 150 °C, and the storage temperature range is specified from -55 °C to +150 °C.
